ColdFusion (2018 release) Update 17

ColdFusion (2018 release) Update 17 (release date, 11 July, 2023) addresses vulnerabilities  that could lead to arbitrary code execution and security feature bypass.

For more information, security bulletin APSB23-40.

We have also updated the lockdown installer for the version in this update. This addresses a security issue. To apply this fix, you should download and install the lockdown installers from Download ColdFusion.

ColdFusion JDK requirements

COLDFUSION 2018 Update 1 and above  

For Application Servers   

On JEE installations, set the following JVM flag, "-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**; !org.jgroups.**", in the respective startup file depending on the type of Application Server being used.

For example:   

• Apache Tomcat Application Server: edit JAVA_OPTS in the ‘Catalina.bat/sh’ file   
• WebLogic Application Server:  edit JAVA_OPTIONS in the ‘startWeblogic.cmd’ file   
• WildFly/EAP Application Server:  edit JAVA_OPTS in the ‘standalone.conf’ file   

Set the JVM flags on a JEE installation of ColdFusion, not on a standalone installation.   

Prerequisites

1. On 64-bit computers, use 64-bit JRE for 64-bit ColdFusion.
2. If the ColdFusion server is behind a proxy, specify the proxy settings for the server to get the update notification and download the updates. Specify proxy settings using the system properties below in the jvm.config for a stand-alone installation, or corresponding script file for JEE installation.
   • http.proxyHost
   • http.proxyPort
   • http.proxyUser
   • http.proxyPassword
3. For ColdFusion running on JEE application servers, stop all application server instances before installing the update.

Installation

For instructions on how to install this update, see  Server Update section. For any questions related to updates, see this FAQ. 

• The update can be installed from the Administrator of a ColdFusion instance or through the command-line option.
• Windows users can launch the ColdFusion Administrator using Start > All Programs > Adobe > Coldfusion 2018 > Administrator.
• Windows 10, Windows Server R2 2012, and Windows Server 2019 users must use the “Run as Administrator” option to launch  wsconfig tool at {cf_install_home}/{instance_name}/runtime/bin.
• If you get the following error when installing the update using the Download and Install option, ensure that the folder {cf_install_home}/{instance_name}/hf_updates has write permission: "An error occurred when performing a file operation write on file {cf_install_home}/{instance_name}/hf-updates/hotfix_017.properties".
• The connector configuration files are backed up at {cf_install_home}/config/ wsconfig /backup. Add back any custom changes made to the workers.properties file after reconfiguring the connector.

Installing the update manually

1. Click the link to download the JAR.
2. Execute the following command on the downloaded JAR. You must have privileges to start or stop ColdFusion service and full access to the ColdFusion root directory.

    Windows: <cf_root>/jre/bin/java.exe -jar <jar-file-dir>/hotfix-017-330143.jar

    Linux-based platforms: <cf_root>/jre/bin/java -jar <jar-file-dir>/hotfix-017-330143.jar

Ensure that the JRE bundled with ColdFusion is used for executing the downloaded JAR. For standalone ColdFusion, this must be at, <cf_root>/jre/bin.

Install the update from a user account that has permission to restart ColdFusion services and other configured webservers .

For further details on manually updating the application, see the help article.

Post installation

After applying this update, you must reinstall any custom hotfixes that might have been applied earlier. The hotfixes are located in the folder /ColdFusion2018/cfusion/hf-updates/hf-2018-00017-330143
/backup/lib/updates.

Uninstallation

To uninstall the update, perform one of the following:

• In ColdFusion Administrator, click Uninstall in Server Update > Updates > Installed Updates.
• Run the uninstaller for the update from the command prompt. For example, java -jar {cf_install_home}/{instance_home}/hf_updates/hf-2018-00017-330143/uninstall /uninstaller.jar

If you can't uninstall the update using the above-mentioned uninstall options, the uninstaller could be corrupted. However, you can manually uninstall the update by doing the following:

1. Delete the update jar from {cf_install_home}/{instance_name}/lib/updates.
2. Copy all folders from {cf_install_home}/{instance_name}/hf-updates/{hf-2018-00017-330143}/backup directory to {cf_install_home}/{instance_name}/
